Unexpected behaviour of nested:define 

           Summary: Unexpected behaviour of nested:define
           Product: Struts
           Version: 1.1 RC1
          Platform: Other
        OS/Version: Other
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: Custom Tags
        AssignedTo: struts-dev@jakarta.apache.org
        ReportedBy: areus@ibit.org


nested:define has an implicit "name" value but it is not recognized by the TEI
class o.a.s.taglib.bean.DefineTei and scripting variables are generated with
type java.lang.String instead of java.lang.Object.


Ex:
We have a bean of class "org.ibit.A" stored unner the attribute "theA", with a
property "b" of class "org.ibit.B"

With bean:define

<bean:define id="theB" name="theA" property="b" />
<%-- 
theB has been created with type java.lang.Object
generated jsp -> java code:
theB = (java.lang.Object)pageContext.findAttribute("theB");
--%>


With nested:

<nested:root name="theA">
   <nested:define id="theB" property="b" />
   <%-- 
   it tries to create theB with type java.lang.String throwing
   a ClassCastException
   generated jsp -> java code:
   theB = (java.lang.String)pageContext.findAttribute("theB");
   --%>

</nested:root>


The offending code seems to be in o.a.s.taglib.bean.DefineTei:

87        String type = (String)data.getAttribute("type");
88        Object name = data.getAttribute("name");
89        Object value = data.getAttribute("value");
90        if (type == null) {
91            if ( (value!=null) ||  (name==null) )
92                type = "java.lang.String";
93            else 
94                type = "java.lang.Object";
95        }

It seems that in line 88 it returns null because it doesn't find the implicit
property name of the tag, so the type gets fixed to java.lang.String because
confition in line 91 returns null.
